FIREPLACE.

Specification of Letters Patent.

Patented May 13,1913.

Application filed December 5, 1912. Serial No. 735,066.

To all whom it may concern.

Be it known that I, Mnnvnv V. Anson), a citizen of the United States, residing-at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in l ireplacos, of which the following is a specification.

This invention relates to improvements in fire-places,and has forits object to provide a novel and simple construction and arrangement of the throat of a fire-place, to the end that a greater amount of heat may be produced and supplied to a room, by

tliedburning of less fuel, than by any other fire-place'known tome.

A further object is to provide etl'ective means for reventing the smoking of the when a fire is started in a amp chimney.

A further and particular object is to provideianovel and simple damper for controlling and regulating the draft in the throat of the chimney and for conserving the heat. And a further object is to provide novel and simple mechanism for operating the damper and other movable parts.

The various features and parts of the invention will be understood from the detail description which follows, and by reference to the accompanying drawing, which forms a part of the specification, and in which- Figure 1 is a horizontal section taken on line l-1 of Fig. t; showing the dau'iper closed; also showing the operating mechanism located at one end of the throat. Fig. 2 is a perspective view of a fire-place having my improvement applied. Fig. 3 is a central vertical section; showing the da1nper in operation; also showing the course of the hot and cold-air currents. Fig. 1 is an enlarged vertical section taken on line 4% of Fig. 1. Figs. 5 and ;,ti.-are respectively a front and side view of the raclebar employed for rocking the damper. Fig. 7 is a front view of the angle-iron which supports the arch. 1

Similar characters of reference are assigned to corresponding parts throughout the several views.

In. the drawing, 2 represents the floor or bottom of the fire-place which is preferably provided with an ash-damper 3.

4 represents the back wall of the fire placef the upper portion 5 of which preferably inclines upwardly from a point near the bottom 2 ,to. a point near its upper end for taugular in form,

,per is held in position by the purpose of deflecting, or compelling the heat from the tire to pass out into the room, and 6 represents the opposite sides or reveals which are splayed or sloped'corl'espondingly, for the same purpose as the back.

7 is the throat of the fireplace, which is formed in the first place by the masonry comprising the upper edges of the back 5 and the reveals (i, and also by the lower rear side of the arch 8. The throat 7 when finished is faced or lined on all sides by series of angular=irons and other parts which comprise the throat frame. The front angleiron consists of a horizontal leaf or portion 9, the opposite ends of which are ()IXlbQCltlGtl in the jams or reveals 6, and this part supports the arch bricks or the masonry The vertical leaf or portion 10 of the said iron lies against and protects the rear side of the arch 8. The rear angleiron comprises a vertical portion 11 which'lies against the front face of the inclined back 5, while the horizontal leaf 12 of the said iron lies upon a comparatively broad shell or ledge 13 which extends rearwardly from the throat into the chimney. The opposite ends of the throat are lined with end plates 14. and 14:. These end plates may be separate parts, or they may be formed with either the front or back angleirons.

The damper employed for closing the throat, as well as for regulating and controlling the draft from the tire-place to the chimney, consists of a substantially flat iron or steel plate 15, which is preferably recand has a greater breadth than the opening of the throat 7. then closed the damper 1.5 is disposed on an incline, as best seen in l figs'. 2, 3 and 4, and when in this position its front edge and its ends rest upon the upper edges of the. irons 10, 1 1 and l t. The rear edge ,of the dam-- per is pivotally lugs 16 which are preferably formed integrally with the rear angle-iron and face the throat. By this arrangement the danigravity without any other securing means, and may be readily and (prickly applied or removed.

The operating mechanism for the damper will now be described.

17 re n-esents a link or lever which is pivoted at one end to lugs 18 carried by the under side of the damper 15. by'a pin or supported between parallel .lugs 27 which depend from the bolt 19. The opposite end of the link is pivoted by a pin 20, to an arm 21 carried by a segment-gear 22, which is pivotally supported and journaled on a stud 23, which is carried by the end iron 14. The gear 22 is rotated by a rack 24, which disposed directly beneath the gear and is mounted upon, or may form a part of, a bar or rod 26 which extends forwardly to the front side of the fireplace. The forward portion of the bar 26 ispreferably a. number of open underside of the soifit iron 9. The extreme outer end of the bar 26 isformed into a loop 28 to which is attached a ring 29, which maybe grasped by the hand for reciprocating the bar, as indicated by the ful and dotted lines in Figs. 3 and 4.

30 represents a spring which is disposed between the underside of thearch iron 9 and the top of the bar 26. This spring is employed for pressing and holding the bar 26 in the bottom of the loops 27 as well as for exerting its tension against the said bar for preventing the accidental ClOSHif of the damper by its own weight. One on of the spring 30 is pivotally secured to the iron 9 by a pin 29', which permits the said flat, and passes through dotted lines in Figs. 1; and '5, for allowing the insertionand withdrawal of the bar'aiid ing it in place.

31 represents a stop which is carried by the bar 26 near the front end of the rack portion. The stop preferably consists of a cotter-pin which pierces the bar and is tem-v ployed for limiting the outward movement of the bar and rack when operated, as indicated by dotted lines in Fig. 4. The stop 31 should be positioned at a point which will allow the damper to be rocked from the closed position, shown by the full lines, to the open position, shown by the dotted lines, in Fig. 4. The rack 24 is so disposed and its teeth are so proportioned that when the bar 26 is pulled out abouttwo inches the damper will be operated to its Wide-open position. The withdrawal of the pins or bolts 19, 20 and 31 allows the damper and its operating parts to be removed readily and quickly.

Tn'order to carry out the full'intent and ob ect of'my invention, certain parts of the interior of the chimney immediately above the throat have been specially designed.

The inner wall of the arch is carried upwardly Vertically for a considerable distance beyond the top edge of the iron 10, as indicated sit-32, so that when theydamper is opened part Way, as shown by the full lines in Fig. 3, as well as, when it is opened go'spring to' swin out as indicated by the.

resume to'thefull extent, as shown hp the dotted lines in Fig. 4, the products 0 combustion are compelled to rise perpendicularly asufiicient distance front side of the throat, and in order to induce the smoke and hot gases to hug the front side of the chimney, the wall is then sloped rearwardly for a distance, as shown at 33. The other variation from the common run of fireplace chimney construction consists of providing the broad shelf or ledge 13 which'lies directly back of, and substantially on a level with the rear-or lowest edge of the damper. This broad ledge notonly provides a roomy space for the accumulation of soot and ashes which gravitates from the chimmy and holds the same clear and free from.

the damper, but 'bybroadening the shelf 13 rearwardly, as indicated, the down-draft, which during the early stages of ..a fire is generally cold and damp, is givena direct and u'nobstructedcourse, and upon impinging thesaid shelf will turn and pass upwardly again, as indicated by arrows in Fig. 3. Where the shelf 13 is made narrow and the front wall 9-32 of the throat slopes rearwardly, the products. of combustion are directed across the flue to the rear wall 34, which diverts the cold and damp downdraft to the front side of the chimney allowing it to force its way into and through the throat, and thus cause the fire-place to belch smoke and reek into the room. But'with my improved construction and arrangement of the throat and dampen-and the provision of the long vertical front wall 32, aswell as the broad rearwardly extending shelf 13, which is preferably broaderth'an the throat, all danger of smoke being forced into the room by the down-draft is obviated. Furthermore by the peculiar construction and arrangement of the throat of the fire-place which consists of a long narrow opening or well extending horizontally between the forwardly sloping back wall 5'and the arch,

to cause them to follow the i and also the positioning ofthe throat entirely above the lower side or edge of the arch, a more satisfactory. and perfect control of the draft is obtained, and when the damper is properly adjusted, a greater amount of heat'is produced from a givenquantity of fuel, andthe heat is thrown into the room without any loss or waste. After the gas and .smoke pass up the chimney, the damper 15 may be entirely closed as shown by the full lines in Fig. 4, and when in this position, the space between the damper and the bottom of the arch comprises a pocket which is immediately filled with the hot air. After this pocket is filled, the rest of the heat will pass out into the room. In order to guard against any gas escaping into the room after the damper is closed, I provide a number of small holes or openin s 35 along the free edge of the damperew 'ch allows the gas to escape from the throat or pocket into the chimney.

It is obvious that some changes or modifications mag be made in the device within the scope efined by the appended claims without departing fromthe spirit of the invention. a

Having thus described my invention What I claim as new and'desire to secure. by Let- .ters Patent is,- 'In a fire-place,

a throat formed by the forwardly inclining back .wall, the sloping reveals, and the vertical Wall of the arch, a metal frame disposed in the throat, one member of said frame adapted to support the said arch, the other member of said frame having parallel lugs disposed at the top of the throat, a damper COIDRIISIIIF a rectangular plate, one edge of sad p ate disposed between, andsupported by said lugs during the opening and closlng movements of said damper, a reciprocatlng rod for operating said damper, and a sprigg adapted to exert its tension against sa1d,r for preventing the accidental closing of said damper.

In testimony whereof I affix-my signature in presence of two witnesses.
